Our Hydrolysed WPI is one of the most advanced whey proteins to assist with gaining lean muscle and/or increasing recovery.

With a degree of hydrolysis of 20.7% and a low average molecular weight of 1400 Daltons, it has very high levels of Di & Tri Peptides which assist with rapid absorption, enabling a quick increase in protein synthesis making it ideal to consume around your workout.

Professional Whey is proud to offer what we consider to be highest quality pre-digested whey protein isolate available in Australia. The facts are:

  • Low Average Molecular Weight of 1400 Daltons
  • High Degree of Hydrolysis at 20.7%
  • High Level of Di, Tri Peptides & other low molecular weight Peptides
  • Over 95% Protein (dry basis), Less than 1% Fat and Carbs

This makes it significantly superior to Whey Protein Isolate and Concentrates but there is evidence that shows Hydrolysed Casein to be a superior choice over Hydrolysed Whey when it comes to muscle gain and fat loss.

However we recommend Hydrolysed Casein and Hydrolysed WPI being used together to get the synergstic benefits of whey peptides and casein peptides.

Note: Hydrolysed WPI has a very bitter taste, due to its hydrolysis. Stevia Extract and Dextrose do mask most of the bitterness. Also the hydrolysis creates a very microscopic fine powder which will froth when shaken, so please gently stir if you want to avoid the frothiness.

    One of the best All Natural HWPIs

    Posted by on 17 Nov 2015

    This product is all natural with no additives and as such is the best supplement for anyone sensitive to lecithins and numerous other additives found in most HWPIs. Additionally, it is fast acting, doesn't leave you feeling bloated and is best value for money. I find it helpful to mix this with natural Rice and Pea proteins to reduce frothiness; stavia for taste and finally Psyllium husk for fibre.

    Hydrolysed WPI

    Posted by on 17 Nov 2015

    I've been using this product for 3 years now, although it has a bitter taste I mix it with coconut water and Professional whey Dextrose which makes it quite pleasant. Wouldn't swap to anything else. Prompt quick Delivery too

    I have used a number of protein products over the years and this is by far the best for results. The high quality fast absorbing protein has allowed for better recoveries. It has an awful bitter taste. I usually counteract this by including some flavored whey isolate. As per price, this is the cheapest, highest quality Hydolysed protein I can find. Well worth the money.

    Fast Acting and Effective

    Posted by on 04 Oct 2015

    I tried this out and am very satisfied with the results. Good diet is one of the keys of success - plug this into your diet and you are set up for success. Add the excellent customer service of Professional Whey into the equation and you can't go wrong.

    Awesome and worth EVERY cent

    Posted by on 29 Apr 2014

    I found this, when used in conjunction with hydrolysed casein, to be very effective when used with an appropriate weight program. I was able to mix it ok, and found the taste, (initially quite different) to be manageable with some of their other products. I would definitely recommend this to anyone who is serious about their training. Fast acting protein, from the purest sources!! 12/10 ;)

    Good results

    Posted by on 16 Feb 2014

    Good results but the taste, OMG ! is just unforgettable.
    I sing nursery rhymes to gather all my courage after putting it on the table, ready to drink. Jingle Bell Jingle Bell or Baa Baa Black Sheep comes out spontaneously when I stare on it. :))

    Very high quality product, even though it tastes quite dreadful, the benefits highly outweigh that only negative, its a small price to pay for the results it brings. Ideal for bodybuilding A++

    Results, and Fast

    Posted by on 14 Nov 2013

    I started using the Hydrolysed WPI about 3 weeks ago and found instantly I was recovering faster. The taste isn't great, but I found I got used to that. This is a great product that is a fresh change to the overpriced protein powders found in supplement stores with a million ingredients. You know exactly what you are injesting and no concerns about artificial flavouring, etc. Tip - was shaker immediately and if left in sun for just half a day it becomes a chemical biohazard!
